GSR turbo with 3" catback is to loud. Can i switch to a 2.5" catback with a resanator with out loosing to much power im running 6 psi, and i wont it quiet but i dont want to loose power what shoud i do guys.
yeah that shouldn't kill that much power because you're not flowing enough to really justify 3" to start w/. I"m going to use 2.5" on my GSR...im hoping for 250ish daily and 315whp at the track.....just to put it in perspective....
